Abstract

In the previous paper [Trans. ISIJ, 11 (1971), 201], the authors reported several results of the electron-microscopic observation on local orientation distributions around large dislocation-free subgrains with their {111} planes parallel to the rolling plane in aluminum-killed steel sheets at the initial stages of recrystallization. The present paper is concerned with the similar observation on the dislocationfree subgrains with their {100}, {110} or {113} planes parallel to the rolling plane. From a large number of data on the local orientation distribution at the initial stages of recrystallization, it is concluded that the recrystallization texture of the aluminum-killed steel sheet developes as a result of the effect of A1N clusters which inhibit the ‘nucleation’ of recrystallized grains from severely bent regions of the deformed matrix and induce the ‘oriented nucleation’ of the {111}‹011›-oriented grains from weakly twisted regions of the deformed matrix.
